I see the action of kneeling on both knees, and lifting one knee, as still kneeling, which is consistent with the Case Book play. And because the player is still kneeling, I don't consider that going from two knees to one is an "attempt to stand." "Standing" must be defined as two feet touching the floor and neither knee touching the floor.
This seems consistent with other rules, such as an airborne player catching a pass from out-of-bounds, or a tip from a jumpball, or a defensive player intercepting a pass and then landing with his/her feet stradling the division line, being allowed to land with either foot first in either frontcourt or backcourt, without a violation. The logic is that a bipedal human is allowed to land on both feet, in such situations, because "standing" is always considered to be on both feet.
In previous discussions of this topic, we haven't arrived at a consensus, and probably won't do so this time around.

It doesn't required standing to be a violation. With your interpretation, the player could essentially stand completely vertical but without touching the 2nd foot to the floor and be legal. "Get up" is also illegal. I read that to be any change of position that is closer to standing than where they start.
